A method, system and computer program product for backup assignment of a mobile electronics device is disclosed. In response to one or more device assignment requests received by a controller apparatus when a server is operating in an off-line mode, one or more device assignment records are created within the controller apparatus, and which indicate assignment of the at least one mobile electronics device to a respective one or more users. When the server is operating in an off-line mode such that communication between the controller apparatus and the server is off-line, the one or more device assignment records, in relation to the at least one mobile electronics device, are stored in the controller apparatus. In response to the server re-entering the on-line mode, the server is updated with the one or more device assignment records.

An electronic device includes a display, a memory, and a processor operatively connected to the display and the memory. The memory stores instructions that, when executed, cause the processor to receive backup data from an external electronic device, identify characteristics of the external electronic device based on the backup data, identify characteristics of the electronic device based on the backup data, at least partially change the backup data based on the characteristics of the electronic device, and display a result of performing a restoring operation based on the at least partially changed backup data on the display.

An approach for staged data backup is provided. The approach comprises downloading data to be backed up, by one or more processors, from at least one of cloud computing servers in a plurality of stages into a local cache, wherein each of the plurality of stages corresponds to a time point when a corresponding downloading operation starts, and a time point corresponding to the last stage of the plurality of stages is the time point when a request to back up the data is received. The approach comprises merging, by one or more processors, downloaded data corresponding to each of the plurality of stages into up-to-date data. The approach further comprises saving, by one or more processors, the merged up-to-date data corresponding to the last stage as a backup dataset.

A computer-implemented method according to one embodiment includes retrieving details of a data backup system; determining whether a first data backup operation will complete within the data backup system before a second data backup operation is initiated within the data backup system, based on the details of the data backup system; and conditionally adjusting one or more elements of the data backup system, based on the determining.

Data recovery systems and methods utilize object-based storage for providing a data protection and recovery methodology with low recovery point objectives, and for enabling both full recovery and point-in-time based recovery. Data generated at a protected site (e.g., via one or more virtual machines) is intercepted during write procedures to primary storage. The intercepted data is replicated via a replication log, provided as data objects, and transmitted to an object based storage system. During recovery, data objects may be retrieved through point-in-time based recovery directly by the systems of the protected site, and/or data objects may be provided via full recovery, for example, within a runtime environment of a recovery site, with minimal data loss and operation interruption by rehydrating data objects within the runtime environment via low-latency data transfer and rehydration systems.

In one embodiment, a system for managing a virtualization environment includes a set of host machines, each of which includes a hypervisor, virtual machines, and a virtual machine controller, and a data migration system configured to identify one or more existing storage items stored at one or more existing File Server Virtual Machines (FSVMs) of an existing virtualized file server (VFS). For each of the existing storage items, the data migration system is configured to identify a new FSVMs of a new VFS based on the existing FSVM, send a representation of the storage item from the existing FSVM to the new FSVM, such that representations of storage items are sent between different pairs of FSVMs in parallel, and store a new storage item at the new FSVM, such that the new storage item is based on the representation of the existing storage item received by the new FSVM.

Techniques for creating and using snapshots may include: receiving a request to create a new snapshot of a source object; determining whether a first generation identifier associated with the source object matches a second generation identifier associated with a base snapshot of the source object; determining whether the source object has been modified since the base snapshot was created; and responsive to determining the first generation identifier matches the second generation identifier and also determining that the source object has not been modified since the base snapshot was created, associating the new snapshot with the base snapshot thereby indicating that the new snapshot and the base snapshot have matching content and denote a same point in time copy of the source object.

Methods and systems for cross cluster replication are provided. Exemplary methods include: periodically requesting by a follower cluster history from a leader cluster, the history including at least one operation and sequence number pair, the operation having changed data in a primary shard of the leader cluster; receiving history and a first global checkpoint from the leader cluster; when a difference between the first global checkpoint and a second global checkpoint exceeds a user-defined value, concurrently making multiple additional requests for history from the leader cluster; and when a difference between the first global checkpoint and the second global checkpoint is less than a user-defined value, executing the at least one operation, the at least one operation changing data in a primary shard of the follower cluster, such that an index of the follower cluster replicates an index of the leader cluster.

An interface for requesting, and technique for generation of, a backup of a past state of a database table are provided. Changes made to a database table are accumulated, in durable storage, and snapshots of partitions of the table are obtained. The accumulated changes and the successive partition snapshots are used to generate a past state of the database at any point in time across a continuum between successive snapshots. Although each partition of the table may have a snapshot that was generated at a time different from when other partition snapshots were generated, changes from respective change logs may be selectively log-applied to distinct partitions of a table to generate backup in the past of the entire table at common point-in-time across partitions.

A system and method for backing up workloads for multiple tenants of a cloud computing system are disclosed. A method of backing up workloads for multiple tenants of a computing system includes triggering an archival process according to an archival policy set by a tenant, and executing the archival process by reading backup data of the tenant stored in a backup storage device of the computer system and transmitting the backup data to an archival store designated in the archival policy, and then deleting or invalidating the backup data stored in the backup storage device.
